Refrigerant Transducer

The Semiconductor Refrigerant Transducer (SRT) is a device that measures the concentration of refrigerants in the air. The SRT can be mounted on a flat surface and is wired to a control system to provide real-time data on refrigerant levels. The SRT can detect various refrigerants, including HFCs, CFCs, and HCFCs. The sensor has a temperature range of 0-95% and a humidity range of 5-8 years.

Product Installation Instructions

1. Mount the SRT to a flat surface using the three mounting holes provided in the back of the housing.
2. With the lid removed, wire the SRT output terminals to the control system. The voltage output terminals are located on connector CN2.
3. Wire 24 VAC power to connector CN1.
4. Replace and secure the lid onto the back of the housing.
5. Once power is applied, the sensor will enter a 5-minute warm-up delay. The sensor should stabilize in approximately 3 to 5 minutes.

To set up the SRT with an E2 input

1. Log into the E2 and press (Input Summary).
2. Highlight the input point the SRT is connected to, and press (Setup).
3. When prompted to select the data type, press (Analog).
4. In the Analog Input setup screen, enter the following information in the fields listed below:
   • Input Type: Analog
   • Input Range: 0-5 VDC
   • Minimum Value: 0
   • Maximum Value: 1000 PPM
5. Press to save changes and exit the Analog Input setup screen.

Input Setup

E2 Input Setup

1. Log into the E2 and press (Input Summary).
2. Highlight the input point the SRT is connected to, and press F1 (Setup). When prompted to select the data type, press (Analog). In the Analog Input setup screen, enter the following information in the fields listed below:

   •   *  **Name:** A description of the sensor’s function and/or location (for example, ZONE1 LEAK).

   • Sensor Type: Refrig. Leak
   • Eng Units: PPM
   • For the SRT, use the default settings. The Refrigerant Leak sensor type default settings are correct for the SRT.
   • Press to save changes and exit the Analog Input setup screen.
